Inflammation
Key to Belly Fat 's Unhealthy Effects
(HealthDayNews, 3/31/05)
Tongjian You of Wake Forest University Baptist Medical
Center, and colleagues, assessed the abdominal fat of 20
post-menopausal women whose waistlines measured over 35
inches. The team checked for three artery-damaging proteins
which fat tissue produces: interleukin 6 and tumor necrosis
factor alpha, which promote inflammation and plasminogen
activator inhibitor, which promotes blood clots. They also
tested for two beneficial proteins: adiponectin, an
anti-inflammatory, and leptin, an energy metabolism regulator.
Eight of the subjects had metabolic syndrome—a cluster of
symptoms including obesity, high cholesterol and hypertension—and these women also had
lower adiponectin levels than the 12 who did not have the
disorder. Since metabolic syndrome is linked with higher
cardiac risk, these findings suggest that when an individual
has body fat that produces low levels of adiponectin, the
person's risk of heart disease may increase. Scientists are
currently studying how drugs, diet and/or exercise may alter
the levels of proteins manufactured by fat tissue.
